more 971114 failure

[neal@ctd.comsat.com]

Here is one example of libio check failure on linux-gnu-i586.

Running ./libio.tests/tfformat.exp ...
Executing on host: /usr/local/src/egcs-971114/gcc/xgcc -B/usr/local/src/egcs-971114/gcc/ ./../tests/tfformat.c  -O3 -I.. -I./..  -DTEST_LIBIO -DTEST_EXACTNESS  -L/usr/local/src/egcs-971114/libraries/libiberty -g -lio -liberty   -lm  -o /usr/local/src/egcs-971114/libraries/libio/testsuite/tfformat   
compiler exited with status 1
output is:
/usr/i586-pc-linux-gnu/bin/ld: cannot open -lio: No such file or directory
collect2: ld returned 1 exit status

Well I'm not surprised it doesn't find libio.  The only libio is
libraries/libio/libio.a, which is not on the link path of this above
compilation, and besides, it is an 8-byte length file (nothing but an
archive header, I guess).
